@lynnesbian @sophia I firmly disagree. Here are the reasons why Gmail is #FOSS:
* No vendor lock in, you can send messages to people who do not use gmail
* No lock in in the UI either, you can use Thunderbird if you choose to and Gmail would still work
* Not only can you view the source code but you can also save it (Ctrl+S) and upload it to your cloud. Giving you the opportunity to have your own Gmail.
* It starts with a G, like GNU
All of this combined is more than enough to call Gmail #FOSS
There's a very strict definition of Free Software, as well as OpenSource, and so F[L]OSS as well.
And they include publishing the source code of the software.
What you see in the browser is the code of the pages that are generated by it, not its own code.
FOSS means Free Open Source Software. If gmail would be foss, it would mean that (providing were talking about the entire gmail email suite) anyone could inspect the source (including server side), host their own instance and redistribute it according to the software license.
Linux fueled mayhem & madness with a side of news, reviews, and whatever the Hell-Elks™ we come up with.
